What does ${} (dollar sign and curly braces) mean in a string in Javascript? -

-

i haven't seen here or on mdn. i'm sure i'm missing something. there's got documentation on somewhere?

functionally, looks allows nest variable inside string without doing concatenation using + operator. i'm looking documentation on feature.

example:

var string = 'this string';  console.log('insert string here: ${string}');

you're talking template literals.

they allow both multiline strings , string interpolation.

multiline strings:

console.log(`foo bar`); // foo // bar

string interpolation:

var foo = 'bar'; console.log(`let's meet @ ${foo}`); // let's meet @ bar
